Market context

Bitcoin’s last trade before the settlement cut-off will decide whether this market resolves above the specified price level on 22 May. The current crowd-implied probability is 0% YES, but that should be read with care: if the event is phrased as a single printed price rather than a daily close, the outcome can hinge on the exact timestamp used by the venue. Comparable Bitcoin threshold markets on Polymarket often show very sharp price clustering around round numbers, while Kalshi-style contracts are usually quoted in implied probability and Betfair or Smarkets in decimal odds, making direct comparison awkward unless fees are included. On exchange-style books, wider spreads and commission can matter more than on prediction markets, particularly if liquidity is thin close to expiry.

Recent context has been mixed but broadly range-bound. Bitcoin spent much of May oscillating around the high-$70,000s to low-$80,000s, with technical commentary focused on the 200-day moving average near $82,228 as the main resistance marker. 24/7 Wall St. said on 1 May that BTC had repeatedly failed to close above $80,000 and expected a May range of roughly $75,000 to $85,000, while Changelly’s May forecast centred nearer $81,500 and Binance’s user-input model pointed to the mid-$76,000s to high-$77,000s. For traders comparing books, the practical catalyst list is narrow: spot ETF flow updates, any Fed-driven risk swing, and whether Bitcoin can hold above the $80,000 area into the settlement window. In a 0% YES market, even a modest rally can matter if it is the difference between a print above or below the threshold.

Methodology

This page compares What price will Bitcoin hit on May 22? specifically across Polymarket, Kalshi, Betfair Exchange and Smarkets. Live odds come from the Polymarket order book; the other venues' contract details are maintained manually because their APIs aren't directly comparable. Every CTA routes to PolyGram, which mirrors the Polymarket order book at 0% fees.

Resolution & payout

Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.

Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
